Smoke from tissue-burning tools like lasers can be toxic to surgical team

Using lasers or cauterizing tools during surgery creates a noxious smoke that can affect the health of doctors, nurses and patients. New voluntary standards were unveiled Wednesday to minimize the number of pathogens that enter health workers' lungs.
Smoke from tissue-burning tools like lasers can be toxic to surgical team

The surgeon touches an area of exposed flesh with a cauterizing tool for less than a minute, sending up a cloud of noxious smoke that quickly wafts across the room and catches at the eyes and throat.

It is only a demonstration - the flesh is actually raw turkey - but the result illustrates the hazard that doctors, nurses and even patients can be exposed to during operations that employ lasers and other tissue-burning tools.

Known as "plume," the smoke is laden with all manner of potentially toxic substances and disease-causing microbes that can make their way past surgical masks and into the lungs.

"According to one study, exposure to (vapours from) one gram of laser-cut tissue is like smoking three unfiltered cigarettes," said Suzanne Kiraly, president of the Canadian Standards Association (CSA), which on Wednesday released new guidelines for capturing and disposing surgical plume.

"Thus far, researchers have identified more than 600 organic compounds in plume generated by vaporized tissue," Kiraly told a news conference at Women's College Hospital in Toronto, where the demonstration took place.

Comment: While reporting on a legitimate problem, mainstream medicine can't resist getting a dig in at smoking. What cigarette or pipe tobacco will ever contain "aerosolized blood and blood-borne pathogens"? The two are hardly equatable.

Silent victims opt for jobs over workplace bullying, sexual harassment complaints

Australian workers are putting up with bullying and sexual harassment because they fear a complaint would mean "career death".

Almost two thirds of Australian workers say they have been bullied at work, and nearly one third claim to have been sexually harassed, according to a survey by employment website CareerOne.com.au. It showed 74 per cent of of sexual harassment cases went unreported, often because workers feared the impact it would have on their job.

Australian Human Rights Commision sex discrimination commisioner Elizabeth Broderick said the findings were no surprise, and said the dire economic climate would reinforce the culture of silence.

"Job security is now seen as all-important," she said. "People will be reluctant to do anything.

"It's too soon to tell, but I would expect (low levels of reporting) to become worse."

Book: Columbine shooters mentally ill, not bullied

Shortly after the massacre at Columbine High School, a question popped into Peter Langman's mind: What would possess a child to pick up a gun, take it to school and mow down his classmates?

His interest wasn't merely academic. Langman, a child psychologist, had been asked to evaluate a teenager who posted a hit list on his Web site.

"To be sitting face to face with someone who was thought to be a potential risk for doing something like a Columbine attack was very intense," Langman says now. "A lot was riding on what we did with him. This was a potential mass murderer."

Since there was very little research at the time to guide him, Langman says, he felt an "ethical obligation" to learn all he could about the psychology of school shooters. The result of his decade-long inquiry: a book that plumbs the lives of 10 notorious school shooters - including Columbine killers Eric Harris and Dylan Klebold and Virginia Tech gunman Seung-Hui Cho - to draw conclusions about what set them off.

US: Shaken baby cases on the increase

Specialists link rise to economic stress

Cases of the potentially devastating brain injury known as shaken baby syndrome have at least doubled in the last few months, a jump that Massachusetts child abuse specialists say is apparently influenced by families' economic stress.

Child protection teams at Children's Hospital Boston and Massachusetts General Hospital, which consult on many of the state's cases of maltreatment, have seen nine infants with shaken baby syndrome in the last three months, compared with four in the same period last year.

The number of cases of brain trauma has increased statewide, officials say, amid an overall rise in child abuse and neglect reports of 8 percent in the 2008 fiscal year, compared with the previous year.

Spinal Taps Carry Higher Risks For Infants And Elderly

An X-ray-guided spinal tap procedure fails more than half of the time in young infants and should be used sparingly, if at all, for those patients, according to a new study done by researchers at Wake Forest University School of Medicine.

The study also shows that the X-ray-guided form of spinal tap, called fluoroscopy-guided lumbar puncture, causes a doubling in risk of bleeding for patients older than 80 compared to younger patients and that the risk of bleeding caused by the procedure can be reduced by doing the puncture at the middle of the lower back rather than at the lowest levels of the spine.

US study: Provigil, a narcoleptic drug, may be addictive

Provigil, a narcolepsy drug increasingly used by healthy people to boost brain performance, may be addictive in vulnerable people and should be monitored, U.S. drug abuse experts said on Tuesday.

A pilot study on 10 healthy men found that at normal doses, the Cephalon Inc (CEPH.O) drug known generically as modafinil increases levels of the reward chemical dopamine in the same part of the brain that becomes active with other drugs of abuse.

"It has the signature that it could potentially be addictive," said Dr. Nora Volkow, director of the National Institute on Drug Abuse, whose study appears in the Journal of the American Medical Association.

Spinal cord device helped mice with Parkinson's

Chicago - A spinal cord stimulator helped rodents with Parkinson's disease move more easily, offering the hope of a less-invasive way of treating the disease in humans, U.S. researchers said on Thursday.

"We see an almost immediate and dramatic change in the animal's ability to function when the device stimulates the spinal cord," said Dr. Miguel Nicolelis of Duke University in North Carolina, whose study appears in the journal Science.

If it works in humans, Nicolelis said, the device could be used to treat the disease early on, reaching far more patients than current stimulators, which are implanted deep in the brain, and can benefit only about one third of Parkinson's patients.

Rights group: 1,000 seized in Gambian witch hunt

Dakar, Senegal -- Authorities in Gambia have rounded up about 1,000 people and forced them to drink hallucinogens in a witch-hunting campaign that is terrorizing the tiny West African nation, an international rights group said Wednesday.

Amnesty International called on the government of President Yahya Jammeh, who seized power in a 1994 coup and has claimed he can cure AIDS, to halt the campaign and bring those responsible to justice.

Gambian officials could not immediately be reached for comment and the government has issued no statements in reaction to the report.

Authorities began inviting "witch doctors," who combat witches, to come from nearby Guinea soon after the death earlier this year of the president's aunt. Jammeh "reportedly believes that witchcraft was used in her death," the London-based rights group said.
